Faroes Islands offshore wells

QEMSCAN cuttings digitalisation of all wells in the Faroes Islands national archive

Rocktype in partnership with Jarðfeingi is generating QEMSCAN 50 mineralogy data for all 9 offshore Faroe Islands wells, from first return to TD.

Deliverables

  • Cuttings photographs and QEMSCAN mineral map images for all samples

  • Per sample lithotype volume %

  • Modal mineralogy, per sample and per lithotype

  • Cuttings size index, per sample and per lithotype

  • Average grain size for all mineral phases, per sample and per lithotype

  • Calculated log values (gamma ray, density, neutron), per sample and per lithotype

Each sample yields a 50 micron resolution QEMSCAN mineral map. Mineralogy by depth is provided in the Rocktype standard grouped (30 entries) and detailed (133 entries) mineral lists. The middle image shows 299 images presented for the example well.

The digitised cuttings are classified into different lithotypes.   The bar chart, left, shows lithotype volume % for the 299 samples in the example well. The scatter graph, centre, shows average cuttings size per sample per lithotype. The pie map, right, shows lithotype volume % for a specific stratigraphic interval for a range of wells.

It is possible to interrogate specific lithotypes of interest. In the example dataset above, data from the Sandstone_Siltstone lithotype is presented for key reservoir units for the well.   The far left graph shows the volume percent of the Sandstone_Siltstone lithotype and the next graph along shows the modal mineralogy for this lithotype only for samples with more than 20% Sandstone_Siltstone.   Further to the right is the average Quartz grain size per sample, for the Sandstone_Siltstone lithotype only.   The four pie diagrams show Sandstone_Siltstone mineralogy for a specific stratigraphic interval for a range of wells.
